Comments on the article

For the first time lamp type QL power of 85 W were used in lamps made in the style of gas lamps and installed in one of the squares of Paris, as well as in the pedestrian part of the Champs Elysees. QL lamps with a power of 55 W were used for the first time in installations with long hollow light guides in the parapet lighting system for pedestrian and bicycle paths of the new bridge in Groningen (Netherlands). The literature provides many examples of the use of QL lamps in outdoor and indoor lighting installations: among them the illumination of the clock on the Beat Ben tower, the lighting of the House of Lords in the UK Parliament, the tunnel on the motorway between the cities of Vevey and Montreux on the shores of Lake Geneva, the railway station for the high-speed express train in Brussels, large shopping malls in Madrid, Barcelona, Hamburg, etc. These lighting fixtures mainly used 165W QL lamps.

Increasing the power of QL lamps above 165 W is limited by the ability to remove heat from the inductor and the permissible levels of electromagnetic radiation.

According to the electric field strength, the maximum permissible level (MPL) of radiation at workplaces during the day for frequencies from 60 kHz to 3 MHz is 50 V / m, and according to the magnetic field strength - 5 A / m. In QL and Genura type lamps, the discharge has some shielding effect on the level of RF emissions from the inductor. The price of the QL kit is about 250 euros. In table. 2.32 are given QL specifications.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Apple's eye-tracking 3D interface 18.02.2012

Apple decided to relate the user interface to the user's position and other external conditions in which he works while operating the phone. The paper was titled "XNUMXD UI Effects on Screen Using Motion Properties".

According to the patent application, a full set of sensors built into mobile devices is used to process the interface: a digital compass, a GPS module, an accelerometer and a gyroscope. They determine the location of the gadget, its orientation, the state of movement and other external conditions with great accuracy. And the front camera "aims" at the user's eyes and tracks the direction of his gaze. The combination of all these elements allows you to create "more realistic virtual 3D images of objects on the screen of the device" on the smartphone screen.

The main difference between stereoscopic screens and real 3D displays is the simple fact that when you change the position of the head, the angle of objects on stereoscopic systems does not change. However, using tracking technology, even on a simple "flat" screen, the illusion of 3D objects can be created. Moreover, the system assumes the use of a light sensor, and if screen objects cast a shadow, then the position of the shadow will change when the display is rotated relative to the light source.
